The 5G version of the Samsung Galaxy S10 – which a lot of people are calling the Beyond X – is in the works.

“T-Mobile is working on that phone too, and other 5G devices with other OEMs and chipset manufacturers,” T-Mobile CTO Neville Ray mentioned.

Verizon showed off this phone at Qualcomm’s Snapdragon Summit, and AT&T and Sprint also confirmed they would carry it.

T-Mobile’s claims Verizon and AT&T’s 5G launches are too early, and T-Mobile’s later, multi-band approach is better and more comprehensive.

The Beyond X’s Qualcomm X50 modem will not only work on T-Mobile’s limited millimeter-wave 5G holdings, but also on Sprint’s 2.5GHz spectrum.

However, if T-Mobile actually does complete its merger with Sprint, the phone will have broader 5G coverage on the merged carrier than it would on AT&T or Verizon.

But, if the merger does not go through, the Beyond X’s 5G abilities would be extremely limited on T-Mobile, because it will not support T-Mobile’s low-band 600MHz 5G system, which has been touted many times as being critical for delivering nationwide coverage.

Support for 600MHz will come with an upcoming Qualcomm chipset that will likely be announced in February,s everal sources have said.

Interestingly, the chipset will be key to a second Samsung phone that AT&T has pre-announced.
